Description

Technical Field

[0001] This utility model relates to the field of diesel generator set supporting equipment, and in particular to a diesel generator set rubber hose fixing device. Background Technology

[0002] In diesel engine systems, rubber hoses play a crucial role, responsible for delivering critical media such as fuel, lubricating oil, and coolant to ensure the normal operation of the diesel engine. However, the proper securing of rubber hoses has always been one of the key factors affecting the performance, safety, and service life of diesel engine systems.

[0003] In existing technologies, rubber hoses are mostly secured using metal clamps, straps, or simple supports, which have the following drawbacks: traditional clamps are prone to hose displacement or detachment under vibration or pressure changes; direct contact between the hose and rigid supports can easily cause surface damage due to long-term friction; tools are required for tightening, resulting in low operational efficiency and difficulty in reuse; furthermore, diesel generator sets generate continuous and strong vibrations during operation, which are transmitted to the rubber hose through the connecting components; the connection between the hose and the connector is a point of concentrated stress, and under vibration, the connection is prone to loosening; once the connection loosens, the medium will leak out from the gaps, affecting the normal operation of the equipment; at the same time, loosening will also increase the relative movement between the hose and the connector, further aggravating hose wear and damage, and shortening the service life of the equipment.

[0004] Therefore, it is necessary to provide a new rubber hose fixing device for diesel generator sets to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a rubber hose fixing device for diesel generator sets.

[0006] The diesel engine rubber hose fixing device provided by this utility model includes: a rubber hose body, a movable joint, a silicone shock-absorbing pad, a locking component, and a fixing component. The rubber hose body is provided with a guide rail on the outside and an arc-shaped rubber pad inside the guide rail. A movable joint is installed at the end of the rubber hose body, and a fixed joint is provided on one side of the movable joint.

The locking component is used to quickly lock the rubber hose body and the movable joint. A fixing component is installed on the side wall of the movable joint. The fixing component is used to fix the movable joint and the fixed joint to prevent loosening between the movable joint and the fixed joint due to vibration.

[0007] Preferably, the locking assembly includes: a fastening ring, a lever bolt, and a nut. The ends of the rubber tube body are symmetrically equipped with fastening rings. One end of the two fastening rings is connected by a hinge, and the other end is provided with a slot.

The other end of the fixing bolt passes through the silicone shock-absorbing pad and the corresponding through hole inside the movable joint and is threaded with a fixing nut.

[0009] Preferably, the fixing assembly includes: a ratchet nut, a pawl, and a spring. The outer wall of each fixing bolt is fitted with a rubber pad, and the end of each fixing bolt is threaded with a ratchet nut. The side wall of the movable joint is equidistantly rotatably connected with pawls corresponding to the ratchet nuts. The pawls are installed in conjunction with the corresponding ratchet nuts. The side wall of the movable joint is equidistantly fixedly connected with mounting plates. The side wall of each mounting plate is fixedly connected with a spring. The outer wall of each pawl is fixedly connected with a protruding rod, and the other end of each spring is fitted onto the outer wall of the protruding rod.

[0013] Compared with related technologies, the diesel engine rubber hose fixing device provided by this utility model has the following advantages:

[0014] Through the design of the fixed components, a ratchet anti-loosening mechanism is adopted in the connection between the movable joint and the fixed joint to prevent the fixing bolts and nuts from loosening due to the vibration of the diesel unit. This anti-loosening mechanism does not require complicated tools. It can achieve a reliable anti-loosening effect simply by rotating the ratchet nut and engaging the pawl. This greatly improves the stability of the connection, avoids medium leakage and equipment failure caused by loose connection, and ensures the normal operation of the diesel unit.

[0015] The locking component design enables quick locking and anti-loosening. This locking component is easy to operate and can quickly achieve a tight connection between the rubber hose body and the movable joint, effectively preventing the rubber hose body from shifting or falling off due to vibration, and further enhancing the anti-loosening performance of the device.

[0016] Silicone shock-absorbing pads can absorb and buffer some of the vibration energy, reducing the direct impact of vibration on the connection parts and lowering the risk of damage to the connection parts due to vibration.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figures 1 to 5 A diesel engine unit rubber hose fixing device includes: a rubber hose body 1, a movable joint 4, a silicone shock-absorbing pad 6, a locking assembly, and a fixing assembly. The rubber hose body 1 has a guide rail 2 on its exterior and an arc-shaped rubber pad 3 inside the guide rail 2. A movable joint 4 is installed at one end of the rubber hose body 1, and a fixed joint 5 is installed on one side of the movable joint 4. A silicone shock-absorbing pad 6 is placed between the movable joint 4 and the fixed joint 5. A locking assembly is installed between the rubber hose body 1 and the movable joint 4 to quickly lock the rubber hose body 1 and the movable joint 4. A fixing assembly is installed on the side wall of the movable joint 4 to fix the movable joint 4 and the fixed joint 5, preventing loosening between the movable joint 4 and the fixed joint 5 due to vibration. The locking assembly includes: a clamping mechanism... The rubber tube body 1 is symmetrically equipped with fastening rings 7, lever bolts 8, and tumbler nuts 9. One end of each fastening ring 7 is connected by a hinge, and the other end is provided with a slot. The side wall of one of the fastening rings 7 is rotatably connected to a lever bolt 8. The outer wall of the lever bolt 8 is threaded with a tumbler 9. The movable joint 4, the fixed joint 5, and the silicone shock-absorbing pad 6 are all provided with through holes at equal intervals. The through holes inside the fixed joint 5 are all inserted with fixing bolts 10. The other end of the fixing bolts 10 passes through the corresponding through holes inside the silicone shock-absorbing pad 6 and the movable joint 4 and is threaded with a fixing nut 11. The surface of the arc-shaped rubber pad 3 is provided with anti-slip texture. The guide rail 2 is made of lightweight high-strength aluminum alloy and is designed as a detachable modular structure, supporting multi-segment splicing to adapt to different length requirements.

[0027] It should be noted that: the fastening rings 7 are used to secure the connection between the rubber tube body 1 and the movable joint 4; one end of the two fastening rings 7 is connected by a hinge, which can be easily opened and closed; after closing the two fastening rings 7, align the slots at their other ends; then, rotate the lever bolt 8 so that it passes through the slots at one end of the two fastening rings 7; the design of the lever bolt 8 allows the operator to generate a large tightening force with a small torque; after the lever bolt 8 passes through the slots, tighten the swivel nut 9; the special shape of the swivel nut 9 makes it easy for the operator to tighten manually without the need for complicated tools; as the swivel nut 9 is tightened, the two fastening rings 7 gradually tighten, applying uniform pressure to the connection between the rubber tube body 1 and the movable joint 4, and firmly fixing the rubber tube body 1 to the end of the movable joint 4.

[0028] Please see Figure 2 , Figure 3 and Figure 4The fixing components include: ratchet nut 12, pawl 13 and spring 14. Rubber pads 15 are fitted on the outer wall of the fixing bolt 10. The ends of the fixing bolt 10 are threaded to the ratchet nut 12. Pawls 13 corresponding to ratchet nut 12 are rotatably connected to the side wall of the movable joint 4 at equal intervals. Pawls 13 are installed in conjunction with the corresponding ratchet nut 12. Mounting plates are fixedly connected to the side wall of the movable joint 4 at equal intervals. Springs 14 are fixedly connected to the side wall of the mounting plates. Protrusions 16 are fixedly connected to the outer wall of the pawls 13. The other end of the spring 14 is fitted on the outer wall of the protrusion 16. Several rubber pads 15 are located between the corresponding fixing nut 11 and ratchet nut 12.

[0029] It should be noted that during the tightening process of the ratchet nut 12, the rubber pad 15 is compressed and undergoes elastic deformation, allowing the ratchet nut 12 to engage with the ratchet when tightened. When the ratchet nut 12 rotates in the tightening direction, the inclined surface of the ratchet teeth pushes the pawl 13 to rotate around its axis of rotation. During the rotation, the pawl 13 compresses the spring 14, and the spring 14 generates elastic potential energy after being compressed. When the ratchet nut 12 rotates through one ratchet tooth, the elastic potential energy of the spring 14 is released, pushing the pawl 13 to reset, so that the tip of the pawl 13 engages in the groove of the next ratchet tooth. As the ratchet nut 12 is continuously tightened, the pawl 13 will be continuously pushed and compressed by the ratchet teeth until the ratchet nut 12 is tightened to the appropriate degree.

[0030] The working principle of the diesel engine rubber hose fixing device provided by this utility model is as follows:

[0031] Before installing the rubber hose body 1, the movable joint 4 and the fixed joint 5 need to be connected first; place the silicone damping pad 6 on the fixed joint 5 on the diesel engine mounting surface to ensure that the silicone damping pad 6 can play a good damping and buffering role; then, place the movable joint 4 on the silicone damping pad 6 so that the through holes inside the movable joint 4, the silicone damping pad 6 and the fixed joint 5 are completely overlapped.

[0032] Use the fixing bolt 10 to pass through the corresponding through holes inside the fixed joint 5, the silicone shock absorber 6, and the movable joint 4 in sequence; tighten the fixing nut 11 on the other end of the fixing bolt 10; during the tightening of the fixing nut 11, the movable joint 4 and the fixed joint 5 are gradually tightened to achieve the initial connection and fixation; at this time, the silicone shock absorber 6 is compressed, which can absorb the vibration generated by the diesel engine to a certain extent and reduce the direct impact of the vibration on the connection part.

[0033] After tightening the fixing nut 11, put the rubber pad 15 on the end of the fixing bolt 10, and then start tightening the ratchet nut 12; as the ratchet nut 12 rotates, the ratchet teeth on its outer wall will interact with the pawl 13 that is rotatably connected to the side wall of the movable joint 4.

[0034] When the ratchet nut 12 rotates in the tightening direction, the inclined surface of the ratchet teeth will push the pawl 13 to rotate around its rotation axis; during the rotation, the pawl 13 will compress the spring 14, and the spring 14 will generate elastic potential energy after being compressed; when the ratchet nut 12 rotates through one ratchet tooth, the elastic potential energy of the spring 14 is released, pushing the pawl 13 to reset, so that the tip of the pawl 13 can be engaged in the groove of the next ratchet tooth;

[0035] As the ratchet nut 12 is tightened, the pawl 13 is continuously pushed and compressed by the ratchet teeth, compressing the spring 14, and then reset and snapping into the next tooth slot. This cycle repeats until the ratchet nut 12 is tightened to the appropriate degree. At this time, under the continuous push of the spring 14, the pawl 13 is always tightly locked in the ratchet teeth of the ratchet nut 12, effectively preventing the ratchet nut 12 from rotating in the opposite direction, thereby preventing the fixing bolt 10 and fixing nut 11 from loosening due to the vibration of the diesel engine.

[0036] Next, one end of the rubber tube body 1 is fitted onto the end of the movable joint 4, ensuring that the rubber tube body 1 and the movable joint 4 fit tightly together; use the fastening ring 7 to lock the connection between the rubber tube body 1 and the movable joint 4; one end of the two fastening rings 7 is connected by a hinge, which can be easily opened and closed; after closing the two fastening rings 7, align the slots at their other ends.

[0037] Then, rotate the lever bolt 8 so that it passes through the groove at one end of the two fastening rings 7; the design of the lever bolt 8 allows the operator to generate a large fastening force with a small torque; after the lever bolt 8 passes through the groove, tighten the tumbler nut 9; the special shape of the tumbler nut 9 makes it easy for the operator to tighten manually without the need for complicated tools; as the tumbler nut 9 is tightened, the two fastening rings 7 gradually tighten, applying uniform pressure to the connection between the rubber tube body 1 and the movable joint 4, and firmly fixing the rubber tube body 1 to the end of the movable joint 4;

[0038] In the entire device, the ratchet anti-loosening mechanism between the movable joint 4 and the fixed joint 5 and the locking assembly between the rubber hose body 1 and the movable joint 4 work together to form a double anti-loosening guarantee. The ratchet anti-loosening mechanism prevents the fixed bolt 10 and the fixed nut 11 from loosening through the cooperation of the pawl 13 and the ratchet nut 12. The locking assembly ensures a tight connection between the rubber hose body 1 and the movable joint 4 through the cooperation of the fastening ring 7, the lever bolt 8 and the nut 9. Even in the continuous and strong vibration environment of the diesel engine unit, these two anti-loosening mechanisms can effectively maintain the stability of the device and avoid medium leakage and equipment failure caused by loosening.

[0039] After completing the above steps, install the other end of the rubber hose body 1 in the same way; place the silicone shock-absorbing pad 6 and the movable joint 4 at the other end on the corresponding fixed joint 5, and connect and secure them using fixing bolts 10, fixing nuts 11, ratchet nuts 12, etc.; then put the other end of the rubber hose body 1 onto the movable joint 4, and secure it using fastening rings 7, lever bolts 8 and swivel nuts 9; in this way, the entire rubber hose body 1 is firmly installed in the diesel engine system through this fixing device, which can stably transport key media such as fuel, lubricating oil, and coolant, ensuring the normal operation of the diesel engine;

[0040] Finally, the guide rail 2 is installed on the outside of the rubber tube body 1 and connected to the movable joint 4 at both ends. The arc-shaped rubber pad 3 inside the guide rail 2 can provide additional support and cushioning for the rubber tube body 1, reducing friction and vibration transmission between the rubber tube body 1 and the movable joint 4. The anti-slip texture on the surface of the arc-shaped rubber pad 3 can increase the friction between the rubber tube body 1 and the guide rail 2, preventing the rubber tube body 1 from sliding inside the guide rail 2.

[0041] The silicone damping pad 6 and the arc-shaped rubber liner 3 inside the guide rail 2 play an important role in damping vibration. The silicone damping pad 6 is located between the movable joint 4 and the fixed joint 5, which can absorb and buffer the vibration generated by the diesel engine, and reduce the impact force of vibration on the connection part. The arc-shaped rubber liner 3 can reduce the vibration transmission between the rubber tube body 1 and the movable joint 4, and reduce the risk of wear and damage to the rubber tube body 1. Through the combination of these two damping measures, the rubber tube body 1 and the connecting parts are effectively protected, and the service life of the device is extended.

[0042] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
